WRENCH-HANDLE.

Specification of Letters Patent.

Patented Mar. 15, 1921.

Application filedOctober 28, 1920. Serial No. 20,141.

T 0 all whom it may concern:

Be it known that I, WILLIAM: J. YVRIGHT, of Baltimore, Maryland, haveinvented an Improvement in lVrench-Handles, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.

This invention relates particularly to handles for double-ended fixedjaw wrenches such as are commonly supplied in sets of three or more forautomobile tool kits. The invention aims to provide a simple and stronghandle for such wrenches which may readily be detached and carriedconveniently within small space, and which may be applied to any one ofseveral wrenches of a set to increase its effective length and enable agreater purchase to be had upon the bolthead or nut.

Further objects and details of the invention appear in connection withthe following description of a preferred form of wrench handle shown inthe accompanying drawings, wherein Figure 1 is a side elevation of thehandle applied to a wrench, shown partly in section to disclose theshape of the socket and fit of the jaw therein, and

Fig. 2 is an edge view of the same.

The handle 11 shown in the drawings has a socket 12 at one end adaptedto receiveeither of the jaw ends 13 of a double-ended fixed jaw wrench.The socket extends through the handle laterally, 2'. c. it opens towardboth sides or edges of the handle, and has a notch or abutment 1 itsinner end to receive the end of one jaw of the wrench which is insertedin the socket, so that the abutment portion lies between the two jaws.

it the extremity of the socket end of the handle there is a tirrupportion or fulcrum which bears against the intermediate shank portion 16of the wrench. T he opening between the fulcrum l5 and the notch orabutment is is long and wide enough to accommodate the jaw end 13 of thelargest size wrench for which the handle is adapted.

The invention is not restricted to wrenches like that shown in thedrawings, as manifestly the socket and fulcrum ma be adapt ed to anywrench having a shank with a bifurcation or jaws at the handle end.

1 claim the following as my invention:

1. A handle for increasing the leverage of a wrench having a shank witha bifurcated end, said handle having a transverse socket to receive thebifurcated end of the vrench, and a fulcrum adjacent to and inlongitudinal alinement with said socket for engaging the shank of saidwrench.

A handle for increasing the leverage of a wrench having a shank with abifurcated end. said handle having a socket opening laterally to receivethe bifurcated end of the wrench, and having an abutment at the innerend of said socket for entering the bifurcation in the wrench, and afulcrum at the extremity of said socket for engaging the shank of saidwrench.

3. A handle for lengthening a double ended jaw wrench, said handlecomprising a socket having a notch adapted to receive either jaw end anda fulcrum to engage the shank the wrench adjacent to the jaw, saidfulcrum and notch being disposed to one side of the center line of saidhandle and socket whereby said handle is reversible upon said wrench toturn it in either direction.

l. A handle 'forlengthening a double enced jaw wrench, said handlecomprising a socket having a notch at its inner end adapted to receivethe tipof a jaw and a fulcrum at its extremity to engage the shank ofthe wrench adjacent to the jaw, said fulcrum and notch being disposed tobear against opposite sides of said jaw and shank, re spectively.

A wrench extension handle having a transversely disposed socket adaptedto receive and hold the free end of a wrench in lo; git-udinal alinementwith said handle and a fulcrum at its tip for engaging the wrenchbetween its free end and jaw end, said socket and fulcrum being inspaced aline ment in the general direction of the length f s id handle.

wrench extension handle having two ely disposed portions near its exityin lengthwise alinement and a transverse opening between them forreceiving the shank end of a wrench, whereby said oppositely disposedportions may engage said shank at different points of its length onopposite sides of its axis.

in testimony whereof I have signed my name to this specification.

WILLIAM J. WRIGHT.
